APPARATUS FOR BORING WELLS.

EI-ECATION forming part of Letters Patent No. 315,826, dated April 1%, 1885.

Application fied March 11, 1884. (X0 model.)

To all whon'z, it may concern.-

Be it known that I, Gus'rilvos PEOH, of Storm Lake, in the county of Buena Vista and State of Iowa, have invented a new and useful Improvement in W'ell-Boring Machinery, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 represents a side view, partly in section,of my improved well-excavator; Fig. 2, a plan of the same, and Fig. 3 an end view; Fig. 4; is a perspective view of the excavating device, partly in section; Fig. 5, a perspective view of the same, showing the hinged bottom; Fig. 6,aview of the coupling on vertical shaft. Fig. 7 is a detail of the shifting miter-wheel S. Fig. 8 shows the gripping device for the augerrod W.

The object of my invention is to provide a new and improved machine for excavating wells, whereby the earth can be moved entirely by means of machinery, all of which will be fully set forth in detail.

In the accompanying drawings, A represents the frame, made in any desirable shape best adapted for the purpose. As shown, it is preferably twice as long as wide, and at one end it has four posts, B, which carry an elevated frame, O. The base-frame A has centrally a cross-piece, thus forming two divisions, A B. Over this latter division,l3,islocated the frame O,which carries the driving mechanism. Over the division A is placed a rim, E, of suitable diameter, which is firmlyheld above the frame in a horizontal position by means of legs E, resting on the frame A. On this rim or within is placed asomewhat smaller rim, F,having a broad annular flange, F, on the upper side, which rests on the stationary rim E. The lower edge of the inner rim, F, is provided with cog-gearing F", as shown.

Suitable means are provided for holding the loose rim and flange down on the stationary rim, and wheels G (see Fig. 2) are placed outwardly from the periphery of the annular flange F to reduce the friction. On opposite sides of the upper surface of this flange F are ears, which carry inwardly the hollow grooved rollers G, the object of which will be hereinafter explained.

On the frame O is hinged a crane or derrick,

H, which carries at the upper end a pulley, H, and loops or eyes may be attached thereto to receive stay-ropes.

K represents a rope which passes over the pulley H, and may connect with swivel fastened to top of square rod W. The opposite end of the rope, after passing over the pulley, extends down to and is wound around the cross drum or shaft L in the frame 6.

One end of the shaft or drum L has a gearwheel, L, which meshes with a smaller gear, M, on the cross shaft M. The shaft Mhas at each end a cranlgwhereby power may be transmitted to the drum or shaft L for the purpose of raising or lowering the auger.

The opposite end of the shaft M has a pulley, N, over which is put a strap-brake, N, one end of which is secured to a bracket or bar, O, on the frame-C, and the other end is attached to a chain, 0, which isin turn attached to a foot-lever, 1?, on the side of the frame below, so that when it is desired the operator can check the speed of the drum or,

stop it entirely by a motion of the foot on the lever P.

Below the crossshaft- L, and parallel therewith,is a short shaft, Q, having at its outer end a pinion, Q, which meshes with the pinion L of drum L.

At the inner end of shaft Q, is a miter-wheel, R, which meshes with a miter-wheel, It, on the longitudinal shaft S, to which power is applied in any convenient manner. The longitudinal shaft S is journaled to the base of the frame A, and extends forward to the rim E, where it is equipped with a miter or bevel wheel, S, which meshes with the cog-gearing beneath the {rim F. The bevel-wheel S is placed loosely on the shaft S, and has a slot cut in its inner face, which engages with a pin through the end of the shaft. Owing to the smallness of the detail in Figs. 1 and 2, this feature is shown in Fig. 9. The miter-wheel It is also placed loosely on the shaft, and has a half-clutch, R, cast therewith on one side. T represents the other half-clutch on the shaft, provided with a groove which operates on a feather on the shaft. The lever T operates the sliding halfblutch, and also the bevel-wheel S, so that when the machine is being operated the shaft S may be kept in continuous revolu- ICC tion and the clutchv arranged to operate the drum and derrick or the boring mechanism as desired by simply reversing the lever.

The excavating device proper consists of the rod W, made in sections as long as desired. This rod is provided with a stirrup, W, disposed in a vertical position, as shown in Fig. 1, through which the rod WV passes. This stirrup is somewhat smaller across the inside diameter of the toothed rim F, and is adapted while in operation to rest against the grooved pulleys G on the rim F. The rod W-is preferably made square, and the socket or hole through the stirrup W is also square, so that when the rim F turns the stirrup will cause the rod W to turn. The lower end of the rod is equipped with a peculiarly-formed excavating or boring tool. This consistsof acylinder, X, rigidly attached to the lower section of the rod W. The lower end or head of this cylinder is composed of two or more curved scoopshaped plates, which form cutting-bits as the cylinder is turned, cutting circular slices of dirt and forcing the same up into the cylinder while revolving. The bottom X of the cylinder is hinged thereto in order that it may be opened to empty the dirt after being removed from the well. Lugs 31 extend downward from the cylinder, and corresponding openings, 3 are placed in the bottom for security in holding in position; during the operationof boring the auger, rod W is disengaged from the hoisting rope or chain K.

When sufficient dirt has been gathered into the cylinderX, the boring machinery is disen- 'tom,by first disengaging the catch on one side of the cylinder by means of a rod, 2, extending to the top of the cylinder, and having on its lower edge a flange or button, 2, which can be passed through the slot 2 in the bottom or. When the rod 2 is turned so as to bring the button at right angles with the slot, the bottom will beheld closed. When turned so as to be in line with the slot, the bottom will fall open.

I claim- .1. The excavating-auger consisting of the cylinder X,.the hinged bottom thereof provided with cutting-blades, the lugs 3 and the disengagingrod z, substantially as described.

2. In combination with the excavatingauger, consisting, essentially, of the cylinder X, having a hinged bottom provided with an opening, 00 the disengaging-rod z, and cut.-

ting-blades and lugs, the frame A, the rims E and F, the cog-gearing F, the wheels G, rod W, andstirrup W, rollers G, and a derrick, all constructed and operated as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, this 6th day of February, 1884, in the presence of witnesses.
